hey jackass this guy is asking if removing and replacing the oil pan has anything to do with or affects the transmission in any way not the oil level or the tranny fluid level as in was the tranny moved was it jacked up or was it removed to replace pan often times there are crossmembers that have to come out in order to replace the pan one would get a new oilpan if it is rusty or some even replace it when the gasket goes because hey why not you are under there no hitting something with your underside does not say that your tranny is hit with something if you have a leaky gasket you replace them he said the grinding started after the repair not before if you arent going to help shut the fuck up no one needs your condescending bullshit
